Android :: Httpclient Redirect Handler
Nov 9, 2010
I'm trying to call a web server that is using relative URL redirects for some of the calls. This of course isn't working with DefaultHttpClient as it isn't treating it as a relative URL. I've gotten as far as implementing a RedirectHandler in an attempt to catch the redirect and add in the base call but I can't work out how to get the location of the redirect.
With the following method how do I go about finding out where I am being redirected to? I can't find any fields on either response or context that have what I need and I don't know where else to look.
public URI getLocationURI(HttpResponse response, HttpContext context)

As I understand by default HttpClient automatically handles Redirect replies from server (follows the redirect link included in the answer from a server). I wonder if and how is it possible to disable this behaviour and handle redirects manually, meaning that I can get redirect link from the reply, modify it and issue a new http request. In a "desktop" version of HttpClient/HttpMethod one can do it as follows:
HttpMethod method = new GetMethod(requestUrl); method.setFollowRedirects(false);
How can I do the same under Android?

I have recently hit a snag using the Android plugin to Eclipse. For some reason, ALL of my errors being thrown don't initialize and show me the error. Has anyone ever seen this issue before and if so, what did you do to correct it? In particular, I am seeing it when I try to invoke the HTTPGet in a HTTPClient object. If I have no connectivity, then I should get an error. The Catch block does fire when this occurs...however, when I check my general Exception object, the object is NULL (NULL Pointer). Why would this happen if the catch is grabbing the exception?
My exceptions used to be working and I was able to see the stack trace. However, I can no longer see any stack trace regardless of the Exception class I am using. Can someone please help me understand what the heck is wrong with Eclipse, Android, or both? Is there something I am missing on the configuration side?...is this a bug? Mind you, I have already used Stack Overflow for this question. It has been viewed 40 times but no answer yet.

I am trying to open a URL using a webview. This URL redirects itself to another page. For some reason the redirect doesnot open up inside the webview. It just opens up into a new browser. Is there some setting in the webview control that can prevent this from happening?

I have a VideoView and I set a VideoURI that is basically http://foo.com/videoName?authentication=xyz When the url is hit, some authentication is processed, then the url gets redirected to rtsp://foo2.com/videoName.3gp for example.
The VideoView seems to not be able to follow the redirect to play the video. If I use the rtsp directly I can play the video though.

I am seeing an issue when using rtsp based URLs on a wap site. If the rstp link has one redirect, then it works and default video player plays the stream. If the rtsp link redirects to another rtsp server and that server redirects to the final destination, then it does not play. Is there a limit in the # of rtsp redirects?

What's the correct way (if any) to redirect a received Intent to another BroadcastReceiver? I have two BroadcastReceivers set to listen to the same intent. It works in development, but in production, only the first one registered in the manifest gets the intent. Can I call the other one's onReceive() method directly, passing the same context and intent? Is there a better way to pass the intent along once the first receiver is done with it?

I met a problem of bluetooth headset. I want to switch audio playing to bluetooth headset when bluetooth headset is paired. I found BluetoothDevice in android sources which can control bluetooth. However it is not contained in android.jar. So I used AudioManager.setBluetoothScoOn(true)
But it still can't work.

For one of my clients they want to redirect customers who are viewing their mobile site from their android to the android market. The url is something like http://market.android.com/search?q=com.company_name , which when clicked on as a link functions correctly but if done as a redirect via php header('location : http://market.android.com/search?q=com.company_name'); will resolve to 404 page not found.
From a pc the link will never resolved, it will only work from an Android phone and only when the link is clicked on via an a href.
Summary
a href='http://market.android.com/search?q=com.company_name' - Works when clicked
header('location: http://market.android.com/search?q=com.company_name'); - Does not work: 404 error

The company I work for is developing an Android App that plays a video file from a URL on web. The
video URL is a parameter for a PHP script that encode it properly and redirects to the encoded video as shown below:
header('Content-Type: video/'.$format);
header('Location:'.$output_video);
Where $output_video is the URL to the encoded video (it works if we use this URL in the browser) and $format is the video format. But when I try executing the MediaPlayerDemo_Video from the API Demos using the streaming mode, I get an error like this:
MediaPlayer Command PLAYER INIT completed with an error or info PVMFErrCorrupt
MediaPlayer error (1. -10)
MediaPlayer Error (1.-10)
If we hard-code the URL and format in the PHP script, it also does not work out, but with a different error:
MediaPlayer info/warning (1. 28)
MediaPlayer Info (1 .28)

One of my users reported that my app wouldn't update over a 3G connection, but would over a WIFI connection. I had him send me a log after a failure and it showed a CircularRedirectException for the URL. Yet, when I try with my phone (3G and WIFI) or the emulator, each with the same request.

I'm trying to implement similar behavior as the native phone app. When a User is in the applications menu/drawer (place that lists all applications) and receives and incoming call, after the call has ended the User is returned to the Android Homescreen. How do I redirect activity to the android homescreen like the phone app for that specific case.

I have a very nice 3G plan on my Samsung Galaxy Tab 2 (P3100) with Ice Cream Sandwich and i want to use the tethering option to share my internet connection and advertise my business through it. I can successfully share my 3G over wifi but i wanna go a step further and install a proxy on my tablet (or something similar) so when someone accesses my tethering wifi connection gets redirected to a webpage of my choise before being able to access any other websites (just like most proxies work in Hotels/Airports etc but without the need of any password, maybe just pushing an "Accept" button after a few lines of info)
I have done a quick search and all i could find is how to connect to a proxy for internet use at my android device or how to setup a proxy server for USB tethering (with software installed at the PC) but i need a softwareless wifi solution based on http headers so that any device can use it.

I haven't used the Java HttpClient before and the documentation is confusing. Say I want to send a POST to the URL "https://domain/foo/ bar". I'm accessing a server with an XML API that defines the message to send like this:
code:.........
And the response to expect like this:
code:..........
Now, I can build and parse the portion inside the serverapi tags but I'm not sure how the HttpClient handles the header. If I use the standard code like this:
code:...........
In the area shown as "not sure", should I pre-pend the entire header in front of the xml section, just as it's shown in the server API document or does the client take care of the first line, since it knows the URL?
Is there a way to see exactly what is about to be sent right before I call HttpClient.execute?
As for parsing the response, I believe I can just do this:
code:..........
Or do I need to strip anything off the response content before I start parsing the xml? I took a few stabs at this and it looks like there's some HTTP bookkeeping information at the start of the response content.

I'm writing a small application which needs httpclient lib, basically to manage the cookie/session automatically. The website I'm targeting needs a valid session, so, between each http call, I need to send the cookie. Httpclient does it well. This is a tv stream application and I have to fetch the channel url, the url has a token parameter and I have to be logged / authenticated / (=> have a valid cookie/sessionid) to fetch the channel url.
I got the first cookie/sessionid with the first connection to the website. The cookie is valid for a certain amount of time, there is no "expires" but I don't know if there is any server cron to cleanup the sessions. I assume I have to "ping" every x secondes to maintain the session valid.
Between each http call, the time could be from 1 sec to several minutes, it depends if the user wants to change the watched tv channel. The http call (to fetch the url) is not made by the UI Thread.
There are several possibilities to manage the httpclient : - a single httpclient static singleton instance accessed by a custom synchronized getClient() on an helper class => when / how to release the http connection ? How to handle that correctly if the user got a phone call / does not use the application for now (unvalidate during onResume, etc)? - Save the cookie (String serialized into SharedPreferences) and create every time a new httpclient instance (then set the cookie to the new instance) => overhead to get the http connection - other ?

I had configure a Tomcat webserver with SSL and client autification. So I need a clienKey.p12 File to visit the site. If I import the key into Firefox, it works fine.
So I tried to develop a Client from "normal" Java. That works:
CODE:..........
Now I try to develope a Client into Android and I am getting crazy....
Here my two Android implementation:
CODE:...........
I always geht the following Exception:
CODE:................
But the key is the same that I use for the "normal" java Client and for the import into firefox. So the key is valid. But it is signed by me... I don't want to sign it by a commercial Company like verisign.

I'm new to implementing HTTPS connections in Android. Essentially, I'm trying to connect to a server using the org.apache.http.client.HttpClient. I believe, at some point, I'll need to access the application's keystore in order to authorize my client with a private key. But, for the moment, I'm just trying to connect and see what happens; I keep getting an HTTP/1.1 400 Bad Request error.
I can't seem to make heads or tails of this despite many examples (none of them seem to work for me). My code looks like this (the BODY constant is XmlRPC):

For example: Say I searched something on the Walmart homepage. Like this. How would I retrieve the information from the first product listed. Information like product name, price, details, rating, model. And how would I search in the box.
The only way it seems like to me is to replace http://www.walmart.com/search/search-ng.do?
search_constraint=0&ic=48_0&search_query=someProduct&Find.x=0&Find.y=0&Find=Find.
Then replace someProduct with the seach and call it in an HttpClient.

I am using httpclient for my android app and I have a local site which has a few https pages. Since default httpclient doesnot allow self-signed certificates I am using "EasySSLFactory" and "EasyX509TrustManager", which are mentioned in httpclient documentation.
CODE:.......
The problem is if I use this SSLFactory in my android app, I am getting correct response from my site's https pages, but I get "SSL handshake failure: I/O error during system call, Unknown error: 0" for sites such as "gmail.com", "ymail.com". If I don't use. "EasySSLSocketFactory" I get response from these sites but get exception for my site.
This page fetch code works fine as a standalone java application.

I'm connecting to a REST service using HttpClient under Android. I'd like to be able to write code where I could pull the host, port, etc. out of a properties file and not have to write fake Schemes and other things like that in order to do the development work. In other words, the live site will have a cert. The dev site will have a self-signed cert or a CA cert. Either way, I need the code to seamlessly work with both kinds of certs if possible. Can someone point me in the right direction?
